摘要： Magnetic display devices include low-density silica coated magnetic and nonmagnetic particles. In a one-particle system, low-density silica coated magnetic particles coated by a sol-gel process are used in combination with non-magnetic particles. In a two-particle system, low-density silica coated magnetic particles coated by a sol-gel process are used in combination with low-density silica coated non-magnetic particles. Display devices employing silica coated magnetic particles minimize the tendency of the magnetic particles to aggregate. Silica coated magnetic particles in a display device results in a magnetic display with improved image stability. Low-density silica coated magnetic particles in a display device allow for particles to move easily through a dispersion fluid in response to a magnetic field.

摘要： A document includes a paper substrate having an average surface roughness of at least about 0.5 microns, wherein the paper substrate includes encoded information printed thereon, and wherein the encoded information is printed with an ink comprised of light absorbing material that absorbs light only at wavelengths below 350 nm and an optional clear binder in a solvent. The encoded information is substantially not detectable to a naked human eye through differential gloss or exposure to light having wavelengths of 365 nm or more, and is only revealed upon exposing the document to light having a wavelength at which the light absorbing material absorbs light, which is less than 350 nm.

摘要： The present disclosure provides toners and processes for making said toners. In embodiments, the toners are invisible when viewed under natural light, but possess a UV emitter that renders them visible when exposed to UV light of a specific wavelength. By selecting the appropriate UV emitter and utilizing an ionic crosslinker, the gloss of the toner may be tailored to match the gloss of any substrate, such as paper, to which the toner is to be applied, thereby further enhancing its invisibility under visible light.

摘要： Disclosed is an item, for example a document, including a substrate having thereon a multiplicity of separate printed markings, wherein the printed markings include both conductive printed markings and substantially non-conductive printed markings. The different conductive and substantially non-conductive regions on the substrate can be detected, for example by measuring the resistance or current of each printed marking. The pattern of different conductive and substantially non-conductive regions can be used as a security pattern of authenticity that cannot be replicated by standard office equipment, and/or can be used to encrypt information in binary code form in the item. A system for forming and detecting the different printed markings is also described.

摘要： An image-forming medium and methods for forming and imaging the medium are provided. The disclosed medium can be strongly colored under room illumination (or deliberate UV) and can be selectively discolored at an appropriate light wavelength to form an image. In one embodiment, the image-forming medium can include a substrate (e.g., a sheet of paper), a photochromic material incorporated with the substrate, and a photo-absorbing material incorporated with the photochromic material. Exemplary methods for using the image-forming medium to make a transient image can include first forming the image-forming medium by applying a coating solution containing photochromic material to the substrate or paper. The image-forming medium can have a medium color and can then be selectively exposed to a radiation through a mask to convert the photochromic material from a colored form to a colorless form and thus to form an image having a color contrast with its background.
摘要翻译：提供了一种图像形成介质以及用于形成和成像介质的方法。所公开的介质可以在室内照明（或有意识的UV）下强烈着色，并且可以在适当的光波长下选择性地变色以形成图像。在一个实施例中，图像形成介质可以包括基底（例如，一张纸），与基底结合的光致变色材料以及与光致变色材料结合的光吸收材料。使用图像形成介质进行瞬时图像的示例性方法可以包括首先通过将含有光致变色材料的涂布溶液涂布到基材或纸上来形成图像形成介质。图像形成介质可以具有中等颜色，然后可以通过掩模选择性地暴露于辐射，以将光致变色材料从有色形式转变成无色形式，并因此形成具有背景色彩对比度的图像。
